Claims. (Cl. 110-18) This invention relates to trash or refuse burners such as incinerators, particularly adapted to be used for disposing of household trash of residences, apartments, office buildings and the like, and in particular an outer drum having a flue adapted to be positioned to discharge into a stack, an inner drum positioned in and spaced from the outer drum, and means for rotating the drums independently, said drums having intake openings therein and the drums being adapted to be turned whereby the intake openings are in registering relation, and said inner drum having air circulating openings therein, the said air circulating openings being positioned at a point opposite to that in which the inlet opening is positioned.

The purpose of this invention is to provide a trash burning incinerator adapted for household use in which the possibility of sparks being carried into the air is substantially eliminated.

Various types of steel and wire drums and containers or baskets have been provided for burning trash and other debris of residences, apartments, and other buildings, however, such devices soon accumulate ashes and it is difficult to clean ashes therefrom. Ashes in burners of this type retard burning as it is difficult to circulate sufficient air through the trash to provide oxygen for combustion. Burners of this type and particularly cylindrical containers of wire mesh are used in back yards and with even a slight wind sparks are carried to dry leaves and adjoining properties.

With these thoughts in mind this invention contemplates an incinerator having a trash burning drum positioned in an outer drum whereby in the burning operation the upper part of the device is closed except a flue opening to a stack, and air for combustion is circulated through openings in the lower part of the burner.

The object of this invention is, therefore, to provide an incinerator in which a trash burning container is surrounded with an outer container and in which trash receiving openings of both containers may be turned upwardly as trash is placed therein and wherein the outer container is adapted to be turned with the opening thereof extended downwardly as the trash is burned.

Another object of the invention is to provide a trash burner for dwellings, office buildings, and the like in which substantially all refuse deposited in the burner is disposed of.

Another object of the invention is to provide a trash burner adapted for individual use in which the parts are adapted to be adjusted to prevent the escape of sparks as in which the escape of sparks is substantially impossible and in which suflicient air may be provided to burn all of the trash, in which the incinerator is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an outer horizontally disposed drum having an elongated opening in the wall thereof and having a flue extended from one end and positioned opposite to the opening, an inner drum also having an elongated longitudinally disposed opening in the wall and also having rows of air circulating openings in the wall and positioned opposite to the elongated opening, a stand in which the outer drum is rotatably mounted, means for rotatably mounting the inner drum in the outer drum, and a stack or flue mounted on one end of the stand and positioned to register with the flue of the outer drum.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure 1 is a side elevational view of the improved trash burner with parts broken away to show the interior construction, and showing the parts in the trash burning positions.

Figure 2 is a plan view of the burner, the parts being shown in positions in which ashes are dumped from the device.

Figure 3 is a plan view similar to that shown in Figure 2 with the parts shown in positions for receiving trash, and with the parts shown on a smaller scale than that shown in Figure 1.

Figure 4 is an end elevational view looking toward the end of the burner on which the fiue is positioned, the parts being shown on an enlarged scale, and parts of the flue and supporting legs being broken away.

Figure 5 is a cross section through the burner taken on line 55 of Figure 3, the drums being shown in positions for receiving trash and other parts being omitted.

Figure 6 is a similar section taken on line 6--6 of Figure 2, the parts being shown on an enlarged scale, and the drums being shown with the openings therein extended downwardly in which position unburned debris is adapted to be dumped from the drums.

Figure 7 is a cross section taken on line 7-7 of Figure 1, with the parts shown on an enlarged scale, and with the drums positioned for burning.

While one embodiment of the invention is illustrated in the above referred to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any manner departing from the spirit and intention of the device, which is to be limited only in accordance with the appended claims. And while there is stated the primary field of utility of the invention, it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, the same reference characters are used to designate the same parts and elements throughout, and in which the numeral 10 refers to the invention in its entirety, numeral 12 indicating an outer drum having a longitudinally disposed opening 14 in the wall thereof and a flue 16 extended from one end, numeral 18, an inner drum having a longitudinally disposed opening 20 in the wall and also openings 22 extended through the wall and positioned opposite to the opening 20, numeral 24 a stack 0r flue positioned to register with the flue 16, numeral 26 a handle for turning the outer drum, and numeral 28 a hand crank for rotating the inner drum.

The drums are positioned on a stand having transverse- 1y disposed end rails 30 and 32, connected to side rails 34 and 36 and supported with posts 38 and 40 at one end, and 42 and 44 at the other. The upper ends of the posts 38 and 40, which extend upwardly from the side and end rails, provide supporting means for a bar 46 uponwhich a bearing 48 is mounted, and, as shown in Figures 1 and 2, a stub shaft 50, which is mounted on an end wall 52 of the inner drum 18, is rotatably mounted in the bearing 48 and the end wall 54 of the outer drum 12 is rotatably mounted on the shaft. The stub shaft extends beyond the bearing and the hub 56 ofvthe hand crank 28 is adapted to be positioned on the extended end of the shaft to provide means for rotating the inner drum 18. A handle 26 is provided on the end of the outer drum 12 to provide means for turning the drum to position the opening therein for receiving trash or the like, and also for turning the flue to correspond with the flue or stack 24.

A bar 60, similar to the bar 46, is carried by the upper ends of the posts 42 and 44 and a stub shaft 62 extended from the end wall 64 of the inner drum is rotatably mounted in a bearing 66 on the bar 60 and an end wall 68 of the outer drum is mounted to turn on the shaft. The bearing 66 is aligned with the bearing 48 at the opposite end of the burner.

Rods or tubes 70 and 72, which are mounted on the rail 30 extend through openings in the bar 60 and the upper ends of the rods extend into sockets 74 in the lower ends of posts 76 and 78 of a flue carrying frame, on the upper end of which is a loop 80 in which a sleeve 82 is carried, and, as shown in Figure 4 the sleeve 82 is formed with a beveled lower end 84 to correspond with the beveled upper end 86 of the flue 16 on the outer drum 12. With the drums positioned for burning trash and the like the opening 14 of the outer drum 12 is located at the bottom and the beveled surface 86 of the flue 16 is in engagement with the beveled end 84 of the sleeve 82 whereby sparks, smoke and the like are drawn into the stack or flue 24.

The pipe 24, which forms a stack or flue, extends upwardly from the loop 80, and the upper end is provided with a rod or spider 88 which supports a pivot pin 90 of a shield 92 that provides a cover for the flue. The member 88 is secured in the pipe 24, such as by welding or the like, and the shield is provided with a weather vane 94, as shown in Figure 1, the vane holding the shield so that it is presented to the wind regardless of the direction the wind is traveling so that down drafts in the flue will be prevented at all times.

With the parts assembled as shown and described the drums 12 and 18 are turned to the positions shown in Figure with the trash receiving openings 14 and 20 at the top and in registering relation, and after trash is placed in the inner drum, the outer drum is turned to the position shown in Figure 7 so that air may circulate through the opening 14 and through the openings 22 into the inner drum to provide air for combustion, and from the fire the gases pass through the opening 20 of the inner drum, and through the flue 16 and sleeve 82 to the stack 24. The height of the stack 24 may be extended so that sparks will be extinguished before being carried from the upper end.

After burning the trash or the like the drums are turned to the positions shown in Figure 6 and ashes or the like are removed therefrom.

From the foregoing specification it will become apparent that the invention disclosed will adequately accomplish the functions for which it has been designed and in an economical manner, and that its simplicity, accuracy, and ease of operation are such as to provide a relatively inexpensive device, considering what it will accomplish, and that it will find an important place in the art to which it appertains when once placed on the market.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size, and rearrangement of details and parts, such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.
